PATTERN FOLLOWED here is,The first Alphabet in each term follows a pattern which is:B + 2 = DD + 2 = FF + 2 = HH + 2 = JThe numbers present in the MIDDLE of each term follows the following pattern:2 × 2 + 1 = 55 × 2 + 2 = 1212 × 2 + 3 = 2727 × 2 + 4 = 58and, the the alphabets in the last of every term follows this pattern:E + 3 = HH + 3 = KK + 3 = NN + 3 = QSo, the next term in the series would be J58Q.Hence, J58Q is the CORRECT answer.
